How to Choose Glass Thickness for AS2047 Certified Windows?

In Australia, windows and doors are more than just a source of light or aesthetic design — they are crucial for safety, comfort, and energy efficiency. Especially for high-rise apartments, coastal villas, or luxury homes, choosing the correct glass thickness is critical. For exported windows, AS2047 certification ensures both performance and compliance.

1. Why Glass Thickness Matters

Glass thickness directly affects wind resistance, watertightness, and sound insulation. In coastal or high-rise locations, thin glass can deform or break under strong wind pressure, while thicker glass ensures stability and safety during extreme weather.

2. Factors in Choosing Glass Thickness

Window size: Larger panels require thicker glass to maintain structural integrity.

Wind rating: The glass thickness should meet AS2047 wind load requirements for the project location.

Insulation and acoustic needs: Double- or triple-glazed Low-E glass improves thermal performance and soundproofing; the thickness and cavity design are critical.

3. Typical Thickness Reference

Small windows: 6mm–8mm single glass or 6+6mm laminated double glazing.

Medium windows: 8mm–12mm single glass, or 10+10mm double Low-E laminated.

Large sliding doors / floor-to-ceiling panels: 12mm–16mm single glass, or 12+12mm double Low-E laminated for maximum strength and stability.
